Role and Future Development of Appropriate Accelerated Corrosion Tests to Simulate Atmospheric Corrosion

Atmospheric corrosion

Atmospheric corrosion, the most common form of metal corrosion, occurs within the interfacial region between a solid, and the surrounding atmosphere. In fact three phases and two interfaces are involved: the gas, a thin liquid layer, a solid, the gas/liquid and the liquid/solid interfaces. In this thesis, the vapor/liquid and liquid/metal interfaces have been studied by the in-situ techniques v...

Atmospheric corrosion

Describe various geographical environments in terms of their atmospheric corrosivity Summarize the main factors causing atmospheric corrosion Explain how these factors are measured Examine how the safety introduced by the massive usage of deicing salts has modified the corrosivity of road environments Design a testing program to establish the corrosivity map of a given site or even a country re...

Spectrophotometric Method for the Determination of Atmospheric Cr Pollution as a Factor to Accelerated Corrosion

The effect of Cr(VI) pollution on the corrosion rate of corrugated iron roof samples collected from tanning industry areas was investigated through simulated laboratory exposure and spectrophotometric detection of Cr(III) deposit as a product of the reaction. The total level of Cr detected in the samples ranged from 113.892 ± 0.17 ppm to 53.05 ± 0.243 ppm and showed increasing trend as sampling...

Microbiologically influenced corrosion: looking to the future.

This review discusses the state-of-the-art of research into biocorrosion and the biofouling of metals and alloys of industrial usage. The key concepts needed to understand the main effects of microorganisms on metal decay, and current trends in monitoring and control strategies to mitigate the deleterious effects of biocorrosion and biofouling are also described. Several relevant cases of bioco...
